Google collects a staggering amount of personal data about its users -- far more than you might even realize. The company records every search you perform and every YouTube video you watch. Whether you have an iPhone ($699 at Apple) or an Android, Google Maps logs everywhere you go, the route you use to get there and how long you stay -- even if you never open the app. When you look closer at everything Google knows about you, the results can be eye-opening, and maybe even a little unsettling. Thankfully, there's something you can do about it.
Starting in June, new Google accounts will automatically delete private data for you. But only after 18 months by default. And only if you're a brand-new Google user.
